CMake error in bcc source compilation

Hi,

BCC build on ubuntu 22.04 fails with below error. Installed clang-14/llvm-14 versions for backend compilation. {{ /bcc/bcc/build$ cmake .. -- The C compiler identification is GNU 11.2.0 -- The CXX compiler identification is Clang 14.0.0 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /usr/bin/cc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Latest recognized Git tag is v0.26.0 -- Git HEAD is 99726b9ece813883b3be3a74d94af634f34bfad2 -- Revision is 0.26.0-99726b9e (major 0, minor 26, patch 0) -- Performing Test HAVE_NO_PIE_FLAG -- Performing Test HAVE_NO_PIE_FLAG - Success -- Performing Test HAVE_REALLOCARRAY_SUPPORT -- Performing Test HAVE_REALLOCARRAY_SUPPORT - Success -- Kernel release: 5.15.0-46-generic -- Kernel headers: /usr/src/linux-headers-5.15.0-46-generic CMake Error at CMakeLists.txt:127 (find_package): Could not find a package configuration file provided by "LLVM" with any of the following names:

The error message

Could not find a package configuration file provided by "LLVM" with any of
the following names:

LLVMConfig.cmake
llvm-config.cmake

shows the bcc didn't find a proper llvm package in the system. You probably missed llvm-dev package. See INSTALL.md file for more details.

Is the problem solved?

[koteswararao18]

Tried to install llvm-14-dev but its in turn triggering libxml2 failure on ubuntu22.04 {{

apt-get install llvm-14-dev

Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:

The following packages have unmet dependencies: libxml2-dev : Depends: libxml2 (= 2.9.13+dfsg-1build1) but 2.9.13+dfsg-1ubuntu0.1 is to be installed E: Unable to correct problems, you have held broken packages. currently looking in to this issue.

@koteswararao18, do you tried reinstall libxml2-dev package? It looks strange that this package is in the list of dependencies for llvm.

I am a beginner, how to solve this problem? OS: ubuntu 22.04

Created bcc/build directory, and then executed cmake in that directory.Unfortunately, ran into the same trouble as them.
